[Gluster-users] nfs

[Antonio Messina]

You can check if the service is enabled with "rpcinfo -p"

you should see a list of services like (output is from Gluster 3.4):

   program vers proto   port  service
    100000    4   tcp    111  portmapper
    100000    3   tcp    111  portmapper
    100000    2   tcp    111  portmapper
    100000    4   udp    111  portmapper
    100000    3   udp    111  portmapper
    100000    2   udp    111  portmapper
    100227    3   tcp   2049
    100005    3   tcp  38465  mountd
    100005    1   tcp  38466  mountd
    100003    3   tcp   2049  nfs
    100024    1   udp  51025  status
    100024    1   tcp  51853  status
    100021    4   tcp  38468  nlockmgr
    100021    1   udp    857  nlockmgr
    100021    1   tcp    858  nlockmgr

You need to have lines for "nfs" and "mountd". If you don't have them
the nfs server is not running.
If it's running you can see which filesystems are exported with "showmount -e":

Export list for gluster-frontend001:
/default *

In my case "default" is the name of the gluster volume exported, and
"*" is the list of allowed clients (in this case: any client)
